CALVIN ELDER, on ST; JOSEPH,

rniirrro sIGNAf.

Application filed February To all whom it mar concern: I Be it known that I, CALt I 'ELDER, a citizen of the United States, residing at St.- Joseph, in the county of Buchanam-State of Missouri, have invented certain'new and useful Improvements 1n Traffic Signals, or

which the following is a specification.

This invention relates to animprovementin traffic signals especially designed for use on automobiles, trucks, or'other vehicles-- The invention aims to provide a tra'liic signal of this character which is of simple and durable construction and easy and -com paratively inexpensive .to manufacture and install and which when in use affords a striking indication of changes in the rate or direction of motion which the driver of the automobile on which the signal is mounted intendsv tomake, the signal being especially designed to give a clear and unmis: takable indication of the intention of the driver of the canto come to a stop or to make a right or left hand turn,

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter -ll'lOlG fully clescribed and-particularly pointed out in the appended claim, reference being had to the accompanyingdrawings forming a part 0 g at 15, are mounted. These panes of glass are this specification, and in which Figure 1 is a perspective view of one form v of the invention,

Figure 2 is a vlew in section showing the v Jacent the mounting of the body on the structure of the semaphore signal arm,

Figure 3 isa fragmentary view partly in section and partly in elevation showing the mounting of the semaphore illustrated in Figure 1, r I

Figure 4 is a 7 view showing a slightly different form of signal mounting and operating means Figure 5 is a view in horizontalsection of the arrangement shown in Figure 4, and

Figure Gis a perspective view showing another form of mounting for the signal.

Referring to the drawings and more especially to Figures 1 to 3, the numeral 1 designates the post of a closed car structure.

In an opening providedin the post 1 a bear-f ing sleeve 2 is fitted and has its ends projectably secured. A shaft 4 is rotatably fitted in the sleeve 2. Adjacent its outer end the fragmentary "perspective k On the projecting ends of the sleeve 2 collars 3 are fitted and suits.

' -shaft 4 is providedwithasquared portion 5, and .on this squared portion 5 a semaphore 6 is mounted, the semaphore having a the squared portlon of theshaft so that t e squared ,ope'ning snugly receivin semaphore is constrained to partake of the rotary motion of the shaft, A nut 'is threadedly engaged with the extreme:end

- A. crank handle 11 is provided and has a hub 12 slidably fitted on the-shaft 4 and held in adjustedlpositionby a set screw 13. The adjustable mounting of the crank hanadapted to the reach of the operator.

The semaphore 6'inc1udes a body made of cast'metal such as alumina or the like or it may be constituted of pressed 'iron or any other. suitable material. Openings 14 are providedin the sides of the body and in these openingslp'anes of glass," designated V dle on the shaft 4 enables'the signal to be translucent but maybe colored or frosted 7 if found desirable.. As indicated at 16 the body ofthe semaphore is made heavieradsquared portion 5 of the shaft '4 and in this heavy portion an opening 17; is provided to receive'a light socket 18. Thelight socket 18 is designed to receive an electric light bulb19 and this socket carries a reflector 20 which is of such a characteras to reflect the light wires 21 extend through an opening 22 provided in the'seinaphore 6 and through light throughout the semaphore whereby 7 both panes .15 are illuminated. Electric an opening 23 provided in. the shaft 4,

These wires are embodied in a suitable light ing circuit which, of course, may include a V 5 shaft .25 which extends fore and aft of the vehicle through a bearing sleeve 27 in a i post 26. A Worm wheel 28 is fixed to the 'hile eceessory is provided; "lhe is illuminated and is clearly vlslhleet 'lllQ'llt as Welles 1n the day.
